My topic is space pollution. This is the debris from satellites explosions, things that fell off liquid that froze in space, and whole satellites that went out of commission. These are in orbit for now, eventually they will reenter earth's atmosphere and hit ground if they don't burn up in the atmosphere. This has been known to happen.
             No great risk is at hand yet, but if we continue to go through business as usual there will be soon. Already there are sign on shuttles that show they have been hit by space debris. On one shuttle a spec of paint left a small crater in its window. In space a piece of aluminum the size of a sugar cube can hit with the force of a 400-pound safe moving at 60 miles per hour. This space debris also falls out of orbit. In one account a fuel tank landed practically intact 50 yards from a man's farm and 125 yards from a busy street. There was another story of some space debris falling that burnt up to just a tiny bit that hit a woman in the shoulder if the debris had not burned up in the atmosphere she would have been killed, but luckily she just attained some burns. These satellites all started going into orbit around the same time. The first satellite, the Sputnik 1, was sent into orbit on October 4, 1957 and the second one went up on November 3 the same year.
             The causes of this are explosions, dead satellites, and in one case a Russian satellites is dripping a coolant that quickly freezes and is up to 2-3 cm in diameter. This space debris is categorized into three areas under 1cm, the size that left that crater in the shuttle window, 1-10 centimeters, and over 10 centimeters in diameters. I don't believe that a law was made.
             We do lose money by having pollution in space. This is because the pollutants hit satellites shuttles and space stations. If these were destroyed shortly after launch that would be a waste of money. One organization says that one of their tes...
